  • The 18th century Joseon(朝鮮) science philosopher Hong Dae-Yong(洪大容, 1731-83) tried to create his own scientific system, while partially keeping the Eastern view of nature and accepting Western science and technology. Most of all, he confirmed that Western science and technology was based on mathematical principles and accurate observation and wrote a math book, [Juhaesuyong(籌解需用)]. Therefore, we have good reason to call him a mathematician. He produced so many achievements that he can be considered a natural scientist in the late Joseon era; he accepted the Eastern view of nature critically and sometimes refused it. He also suggested new and various scientific thoughts, including an infinite universe theory, on the basis of Western scientific thought. Hong Dae-Yong emphasized the importance of practice. He understood the principle of the Western Honcheonui(渾天儀) and manufactured an alarm clock with a craftsman's help. He was an excellent engineer and he set a personal observatory. Considering the level of scientific technology at that time, it is reasonable to regard Hong Dae-Yong as a 'scientific technologist in the 18th century Joseonera', well equipped as a mathematician, a natural scientist, and an engineer. In conclusion, it is with 'mathematical thinking, creative conception, and practical activities' that Hong Dae-Yong maintained throughout his life that we can set a guide to produce excellent Korean scientific technologists and engineers in the 21st century.

  • This study is about a life history. Through investigating the life of retired teachers in preschool, elementary, and middle schools, authors wanted to explore the meaning of retirement and the process of adaptation to find out their personal and social needs in post-retirement life. Studies have shown that their experiences at childhood have greatly influenced the performance of one's profession, such as contributing to setting limits on behaviors of their students. In the period of interdependence, they have contributed to serving society and the nation beyond as a professional, and in the second half of his teaching career, they have learned that their painful experience was a resource and have realized that changing mind can make the world changed. Since teachers' behavior affects on many subjects unlike other jobs, rewards or satisfaction from the job was bigger than any other jobs. However, after retirement, they felt a sense of emptiness in life without any sense of belonging or accomplishment, while feeling happiness and infinite freedom in other hand. Thy still go forward for life challenging to new study.

  • In this rapidly changing era of infinite competition, many companies highlight the importance of internal resources to secure competitiveness. Especially in the service industry, because hotel employees provide service face-to-face with customers, their attitude at the moment of truth directly affects the customers satisfaction and consequently it is directly related to the survival and development of organization. The purpose of this study is to investigate the effect of transformational leadership of hotel managers on self-efficacy, organizational commitment, and job performance. This research aims to provide theoretical and practical implications through the exercise of manager's leadership in the hotel industry. As a result of the analysis, transformational leadership, self-efficacy, and organizational commitment have partially significant positive(+) effect on job performance. Thus, hotel managers should present a strong vision, establish the sense of target and show a careful and persistent interest on individuals to derive voluntary participation and creativity.

  • Infinite failure NHPP models presented in the literature exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, exponential distribution and Rayleigh distribution model was reviewed, proposes the mixture reliability model, which made out efficiency substituted for situation for failure time Algorithm to estimate the parameters used to maximum likelihood estimator and bisection method, model selection based on SSE and Kolmogorov distance, for the sake of efficient model, was employed. Analysis of failure using S27 data set for the sake of proposing shape parameter of the mixture distribution was employed. This analysis of failure data compared with the mixture distribution model and the existing model(using arithmetic and Laplace trend tests, bias tests) is presented.

  • The natural disaster occurrences and the loss of lives caused by the steep-slope failures in Korea were investigated in this study. The investigation includes the frequency rate of the steep-slope failures with respect to the characteristics of precipitation, underlying bedrock, and weathered soils. Analysis on the problems in the existing estimation methods of steep-slope failure was also undertaken, and a new model using unsaturated infinite slope stability was developed for the better slope failure estimation. The slope analyses by the newly developed model were performed considering unsaturated infinite slope, the gradient of slope, and hydro/mechanical properties of soils. Steep-slope failure estimation criterion is proposed based on the analysis results. In addition, the precipitation amount corresponding to warning stages against steep-slope failure is provided as an equation of Intensity-Duration criterion.

  • Die vorliegende Untersuchung zielt darauf ab, erstens die Entstehung der $Fr{\ddot{u}}hromantik$ in Bezug auf damalige Kantkritik zu betrachten, zweites Jacobis Gedanke, der die Bewegung der $Fr{\ddot{u}}hromantik$ $ansto{\ss}t$, mittels seines Zentralbegriffs "Unbedingtes" und "$Gef{\ddot{u}}hls$" zu rekonstruieren und drittens den Kerngedanke der $Fr{\ddot{u}}hromantik$, der die unendliche $Ann{\ddot{a}}herung$ betont, durch Novalis zu $erl{\ddot{a}}utern$. $F{\ddot{u}}r$ Jacobi wird das Unbedingte als "Glaube" angesehen, weil es nicht nur der $M{\ddot{o}}glichkeitsgrund$ des Wissens ist, sondern die Vermittlung des Wissens ${\ddot{u}}berschreitet$. $W{\ddot{a}}hrend$ es die Bedingung des Wissens ist, ist es das "Sein", das den Bereich des $Bewu{\ss}tseins$ transzendiert. Somit Jacobis "Unbedingte" bzw. "Ur-Sein" ist nicht nur die Grundlage des metaphysischen Monismus, sondern die realistische Substrat, die auf den Bereich des Wissens nie reduziert wird. $F{\ddot{u}}r$ Novalis wird das Unbeclingte dem $Bewu{\ss}tsein$ nicht gegeben, vielmehr ist es der Gegenstand der Sehnsucht und des Strebens. Hier wird die Philosophie als unendliche $Ann{\ddot{a}}herung$ zum Unbedingten bestimmt. Philosophie ist sowohl die $urspr{\ddot{u}}ngliche$ $T{\ddot{a}}tigkeit$ des mit dem Transzendeten $ber{\ddot{u}}hrenden$ $Gef{\ddot{u}}hls$ als der unendliche Trieb, der den Grund zu erkennen versucht.

  • With the change into knowledge-based society and infinite competition, sharp employment competition causes anxiety about their own future among college students going into society, consequently making their employment one of the greatest social problems. As schemes of improving the employment rate for seniors at the department of health science, department professors are required to reinforce employment-related interviews as a provider of information about employment and colleges need to set and implement a specific support plan, for example, by encouraging trips for employment guidance at diverse regions. As an effort for qualitative improvement, colleges are required to develop an employment-based curriculum and support basic employment preparations and academic advisers need to serve as a guide specializing in employment as well as an employment-related information provider.

  • 문헌정보학 전공자에게 있어 취업의 꽃은 대학도서관 사서로의 진출이 아닐까 싶다. 왜냐하면 대학 도서관은 다른 관종의 도서관에 비해 외형적으로 규모가 크고, 업무는 다양할 뿐만 아니라 영역별로 전문화되어 있어 다양한 경험을 쌓을 수 있는 장점이 있다. 게다가 근무시간이나 급여, 복지 등과 같은 근무조건 및 환경 역시 타 관종에 비하여 비교적 우위에 있다고 하겠다. 때문에 전공자들 사이에는 기회가 된다면 누구나 대학도서관 사서로의 꿈을 꾸는 것이다. 하지만 최근 대학을 둘러싼 내외적인 상황이 그리 만만하지가 않다. 대학 외적으로는 대학 간 무한경쟁 체제의 확산 및 심화, 입학자원의 절대적 감소, 정부 및 각종 기관의 지원시 엄격한 평가 적용 등의 영향과 내적으로는 대학내 도서관 위상의 점진적 약화, 사서적인 수의 감소, 사서직에 대한 전통적 인식 약화로 인한 입지 위협 등으로 인하여 대하교직원 채용에 있어 도서관 사서는 대개 후순위이거나 고려대상에서 점점 더 멀어지고 있는 실정이다. 또한 최근에는 긍적적 측면과 부정적 측면이 상존하는 사서직원의 본부부서 이동 역시 늘어나고 있다고 하겠다. 한편 1987년 사서자격증 발급자가 2,000여명을 돌파한 이래 최근에는 매년 2,400여명 내외의 자격증 소지자를 배출하고 있는데, 본 글은 이 정도의 공급에 미루어 볼 때 전체 관종 대비 대학도서관 사서의 모집현황은 어느 정도인지? <사서e마을> 정규직, 비정규직 코너에 2007~2010년간 게재된 모집 공고 중심으로 월별, 지역별, 대학 설립주체별 현황 분석 및 전망을 해보고자 한다.

  • Online games take place by the interactions among users and their contents change endlessly with their organic characteristics. Especially, digital images that make a great impact on game play such as characters or items form their own value beyond the establishment scope of their designer even outside of the game world. The users who pay fees for using them establish the concept of possession for the images and information designed in the games. Then, business transactions are formed among them who are in agreement with their values and their possession rights can be changed. In this way, digital images in the online games form new values by the interaction among other users or game systems. Meanwhile, the more the interaction and a sense of solidarity in the community increase, the higher their value becomes.
